Answer from: karyme12

1.2 x 10 -7

Step-by-step explanation:So we wanna know what 0.000012 is in scientific notation.

With scientific notation, you want to end up with something that looks like number times ten raised to the power of x, which would look like:

numberx10x.

The number in the front must always be more than 1, but less than 10. This means the number can be anything from 1.0 to 9.9.

So for the problem you have here we have 0.000012. This means the smallest number in the front could be 1.2 Not 12 and not .12 The number in the front must always be more than 1, but less than 10.

So now we have the first part of the scientific notation: 1.2x10. To know what power to raise the 10 to, count how many zeros there are to the right after the decimal. With our 0.000012, there are 4 zeros, which means 4 spaces to the right, so the 10 would be raised to -4

BUT if we raised that 10 to the power of -4, our notation would look like 0.12x10-4 and remember, that first number cant be lower than 1.

step-by-step explanation:

Answer from: Quest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

$ab^2+ac^2=bc^2$

$ab^2+ac^2=x^2$ )

triangle abd and cba are similar,

$\frac{ab}{bc}=\frac{bd}{ab}$

$ab^2=bc\cdot bd$

$25=bc\cdot bd$ (2)

triangle cad and cba are similar,

$\frac{ac}{bc}=\frac{cd}{ac}$

$ac^2=bc\cdot dc$

$7\times 7=bc\cdot dc$

$49=bc\cdot dc$ )

using (1), (2) and (3), we get

$25+49=x^2$

$74=x^2$

hence proved.

therefore option 2 is correct.
